Please may I have clear workout of this question showing explanations if necessary will greatly appreciate it.

A ball is submerged in a water tank and tethered by a string to the lower surface of the tank. If the ball has a density of 45kg/m3 and a volume of 2.5m3, what will be the tension of the string in Newtons? Take the density of water to be 1000kg/m3.
